According to the cargo handling tray of the present invention, the unnecessary of arrangement of goods is unable to due to not formed around placement surface 1 Space, therefore placement surface 1 can be effectively utilized.

Goods is loaded to the efficiency in container or warehouse therefore, it is possible to significantly improve.

Description below to each example based on the assumption that, i.e., all four edges 3 of placement surface 1 are in whole length Or be formed as eaves shape edge 3 ' in a part of length.However, as described above, present invention encompasses wherein eaves shape edge 3 ' formed to exist In the whole length or a part of length at least one edge 3 of placement surface 1 and recess 4 is limited to the lower section of eaves shape edge 3 ' All structures.

Hereinafter, the premise structure according to cargo handling tray of the invention will be described.According to the cargo handling of the present invention Tray is based on following premise, i.e., this cargo handling tray is for using fork truck, (fork truck to be provided with as shown in Figures 2 and 3 11) cargo handling work that fork is implemented.In other words, cargo handling tray is based on following premise, that is, inserts and remove fork 11, The upper surface 12a of the distal end 12 of the fork tilts down towards sophisticated 12b.

Fork 11 with said structure is preferably by taking the fork of the roll-type including roller conveyor 13 11 as shown in Figures 2 and 3 as an example. The roller conveyor 13 being included in roll-type fork 11 includes multiple upper roll 13A and multiple lower rollers 13B.Roller 13A and 13B connect each other Close, rotated along opposite direction, and supplement the movement of the fork 11 on tray support surface G and fill tray, goods etc. It is downloaded on fork 11/is unloaded from fork.

For example, with reference to figure 3, when fork 11 moves (fork 11 moves forward) and lower rollers 13B and tray along left direction When support surface G is contacted, lower rollers 13B is to correspondingly anticlockwise, and upper roll 13A is to correspondingly right rotation.Under therefore, because Portion roller 13B rotation, fork 11 can swimmingly move forward on tray support surface G, and due to upper roll 13A rotation Turn, can be by the guiding such as tray, goods to fork 11.

On the contrary, working as, fork 11 moves (fork 11 is moved rearwards) along right direction and lower rollers 13B supports table with tray When face G is contacted, lower rollers 13B is to correspondingly right rotation, and upper roll 13A is to correspondingly anticlockwise.Therefore, because lower rollers 13B rotation, fork 11 can be swimmingly moved rearwards on tray support surface G, and due to upper roll 13A rotation, can Guided so that tray, goods etc. are channeled out into fork 11 to tray support surface G.

Figure 1A and 1B is the view for the cargo handling tray for showing the example 1 according to the present invention.According to the goods of this example Thing handling tray includes above-mentioned basic structure, and is especially characterized in that being formed as over the entire length for placement surface 1 Four edges 3 at eaves shape edge 3 '.

<<The structure at eaves shape edge and recess>>

Hereinafter, the eaves shape edge 3 ' of placement surface 1 and the recess being limited to below eaves shape edge 3 ' be will be described in detail Structure.

As shown in Figure 1A, 1B and 4A, eaves shape edge 3 ' has including being dipped down towards (tray central side) on the inside of tray The a of lower surface 3 ' of oblique plane, and eaves shape edge also has and the upper surface 12a of the distal end of fork 11 cunnings on a of lower surface 3 ' The c of slidably contacting section 3 ' of dynamic contact.The a of the lower surface 3 ' b of bottom 3 ' is connected to ground contacting surface 2.In the present invention, it is sliding The dynamic c of contact portion 3 ' refer to the upper surface 12a sliding contacts of a of lower surface 3 ' at the eaves shape edge distal end with fork region or Part.

Because a of lower surface 3 ' at eaves shape edge is configured to tilt as described above, thus a of lower surface 3 ' can swimmingly with The upper surface 12a sliding contacts of the distal end of fork, and near-end (the inner) side at eaves shape edge 3 ' can be strengthened.Due to eaves shape edge The a of the lower surface 3 ' b of bottom 3 ' be connected to ground contacting surface 2, therefore enhance the intensity at eaves shape edge 3 '.

In the case where a of lower surface 3 ' at eaves shape edge as described above is configured to inclined surface, the lower surface at eaves shape edge The upper surface 12a of the distal end of 3 ' a and fork is the plane along inclined.Thus, in order that the c shapes of slidably contacting section 3 ' So as to the reliably upper surface 12a sliding contacts with the distal end of fork on into a of lower surface 3 ' at eaves shape edge, the distal end of fork it is upper Surface 12a inclined angle alpha and a of lower surface 3 ' at eaves shape edge angle of inclination beta are set as meeting α>β relation.

Recess 4 is recessed space, and the top surface in the female space is a of lower surface 3 ' at eaves shape edge, and recess 4 limits It is scheduled on the lower section at eaves shape edge 3 '.The upper surface 12a of distal end for wherein pitching contacts the a's of lower surface 3 ' at eaves shape edge first The c of slidably contacting section 3 ' situation, the depth L1 of recess 4 are set greater than the intubating length L2 of fork.Specifically, depth L1 is set Into meeting L1>L2.In other words, the intubating length L2 of fork is determined by the height of the c of slidably contacting section 3 ' bottom, and recessed The depth L1 in portion 4 is set to more than L2.

Therefore, according to the cargo handling its construction of the present invention into the eaves shape edge 3 ' and recess for causing there is said structure 4 coordination with one another.Thus, as described below, the distal end 12 for pitching 11 is readily inserted in ground contacting surface 2 and tray support surface G Between, and it is finally inserted into whole fork 11.

More specifically, as shown in Figure 4 A, fork 11 moves forward first, until the upper surface 12a of distal end is connected to eaves shape Untill on a of lower surface 3 ' at the edge c of slidably contacting section 3 ', tray can visually be checked by recess 4 during this period Support surface G.For example, as shown in Figure 8, in the case that tray support surface G is lower cargo C top surface, fork 11 can also move forward, while vision and effectively inspection tray support surface G.

Because a of lower surface 3 ' at eaves shape edge 3 ' is to inclination on the inside of tray, therefore the distal end 12 of fork 11 can swimmingly insert Enter in the recess 4 below a of lower surface 3 '.Because the depth L1 of recess 4 is bigger than the intubating length L2 of fork, therefore the point pitched End 12b is not collided unnecessarily with tray.

Next, when fork 11 moves further along as shown in Figure 4 B, the c of slidably contacting section 3 ' at eaves shape edge 3 ' With the upper surface 12a sliding contacts of the distal end of fork, and eaves shape edge 3 ' is raised, so as in ground contacting surface 2 and Fork insertion occurs between the tray support surface G for contacting and (being covered by ground contacting surface 2) with ground contacting surface 2 Gap 14.Thus, the sophisticated 12b of fork can be promoted further along, without any collision occurs, and pitch 11 distal end 12 It is readily inserted between ground contacting surface 2 and tray support surface G, being thus finally inserted into whole fork shovel 11.

Pitched as fruit fork 11 is configured to above-mentioned roll-type, once fork 11 moves forward until ground contacting surface 2 and upper roll 13A Contact, then due to upper roll 13A rotation, whole tray can be swimmingly guided to fork 11.

When removing fork 11 between ground contacting surface 2 and tray support surface G, it is obvious that eaves shape edge 3 ' follows The step opposite with insertion.As fruit fork 11 is configured to roll-type fork, then due to pitch 11 be moved rearwards when the upper roll 13A that occurs Rotation, tray can be effectively guided to leave fork 11 and guide to tray support surface G, thus, it is possible to easily remove fork 11.

Therefore, because the cooperation between eaves shape edge 3 ' and recess 4, can be filled without using the heaviness of such as push-pull device at fixed Implement cargo handling work just with fork 11 in the case of putting, and significantly improve operating efficiency.

The architectural feature of this example is that multiple t loss of weight portion with bottom are set in placement surface 1 and ground contacting surface 2 Divide 9.It is thereby possible to reduce the weight of whole cargo handling tray, and make it possible to carrying out nesting without using period.

The details of loss of weight part 9 with bottom is as follows.As shown in fig. 14 a, in placement surface 1, with along the longitudinal direction The placement surface center for being formed with equal spacing a large amount of depressions that assume diamond in shape in central area with the mode of horizontal direction alignment subtracts Weight part 9a.Preferably, equally as shown in Figure 15, placement surface center loss of weight part 9a part is formed as step-like and put The a of centre of surface loss of weight part 9 ' is put, it is nested to be enable to half.As shown in Figure 14 B, in ground contacting surface 2, with The adjacent placement surface center loss of weight part 9a corresponding mode in interval is formed in central area to be recessed with grid shape Ground contacting surface center loss of weight part 9c.

In a of lower surface 3 ' at eaves shape edge region, multiple eaves shape sides of rectangle taper depression are formed with equal spacing Edge loss of weight part 9d, the summit of the eaves shape edge loss of weight part 9d is close to placement surface 1.Thus, the lower surface at eaves shape edge 3 ' a are discontinuous surfaces, and can reduce because of the upper surface 12a sliding frictions of the distal end with fork and caused by frictional force. In the upper surface at eaves shape edge 3 ', form multiple eaves shape edge loss of weight part 9b, the eaves shape edge loss of weight part 9b with The shaped depressions consistent with a of lower surface 3 ' at eaves shape edge shape.

In the present invention, the shape of the loss of weight part 9 with bottom is clearly not limited to example shown.Do not limit specifically and subtract The shape of weight part 9, if can realize weight reduce and it is nested both.

It is vacuum/pressurized as known to the cargo handling tray use with multiple loss of weight parts 9 with bottom in this example Molding technique is made up of synthetic resin material.

As described above, according to the cargo handling tray of the present invention, can be realized in a manner of being highly successful to goods is filled It is loaded into the improvement of container or the efficiency in warehouse and the improvement of the operating efficiency to cargo handling work.

In the present invention, the lower surface 3'a of placement surface 1, ground contacting surface 2 and eaves shape edge can include recess The discontinuous surface of (such as hole and groove), as long as may insure corresponding function.
